Despite these advantageous properties, challenges such as poor formability and susceptibility to corrosion have restricted its broader application. This review critically addresses these limitations by delving into Mg's biodegradation mechanisms and the various degradation modes activated by different physiological environments. Emphasis is placed on understanding these processes to optimize Mg's utility as a biomaterial. Additionally, the transformative potential of integrating rare-earth (RE) elements into Mg alloys is explored. These elements significantly refine the microstructure, enhance mechanical properties, and improve corrosion resistance, effectively mitigating some of Mg's inherent limitations. Rare earth elements (REEs) significantly improve the mechanical properties of magnesium alloys. Cerium and lanthanum form protective oxide layers, reducing corrosion. Neodymium prevents hydrogen embrittlement, while yttrium refines grain size. The combination of REEs offers a diverse range of properties, including enhanced strength, creep resistance, high-temperature performance, corrosion resistance, ductility, and toughness. This versatility allows for tailored alloy selection for specific applications. The review also assesses the effects of various RE elements on biodegradability, cytotoxicity, and biological interaction, which are crucial for medical applications. Furthermore, the innovative realm of additive manufacturing (AM) is investigated to develop efficient Mg-RE-based biomedical implants, enabling the precise customization of implants to meet individual patient needs. Through a comprehensive evaluation of the latest research, this study projects the promising future of Mg-RE alloys as groundbreaking biomaterials poised to redefine medical implant technology with their superior mechanical and biological properties.","PeriodicalId":16214,"journal":{"name":"Journal of Magnesium and Alloys","volume":"20 1","pages":""},"PeriodicalIF":17.6,"publicationDate":"2024-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142594323","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is found that the twins are first nucleated and grow at a compressive strain of 3% along the RD. In addition to the Schmid factor (SF), the strain coordination factor (<em>m'</em>) also influences the selection of the twin variants during the twinning process, resulting in the nucleation of twins with a low SF. During the second and third steps of the application of continuous compressive strains with magnitudes and directions of 3%RD+3%ND and 3%RD+3%ND+2.5%ND, detwinning occurs to different extents. The observation of the detwinning behavior reveals that the order in which multiple twins within the same grain undergo complete detwinning is related to Schmid law and the strain concentration, with a low SF and a high strain concentration promoting complete detwinning.

The applications in these industries necessitate the accurate prediction of fatigue life under cyclic loading. However, this is challenging for many wrought Mg alloys owing to their pronounced plastic anisotropy. Conventional predictive methods such as the Coffin-Manson equation require manual parameter adjustment for different conditions, thus limiting their applicability. Accordingly, a novel predictive model for low-cycle fatigue (LCF) life that combines machine learning (ML) with an energy-based physical model, referred to as the hybrid ML/E model, is proposed herein. The hybrid ML/E model leverages a substantial hysteresis-loop dataset generated from LCF tests on a rolled AZ31 Mg alloy to effectively predict fatigue life. The proposed approach addresses the inherent challenges of small fatigue datasets, hysteresis-loop perception, and algorithm selection. The hybrid ML/E model demonstrates superior predictive accuracy and robustness in various loading directions, based on validation against conventional methods. The integration of ML and physical principles offers a unified framework for the LCF life prediction of anisotropic materials and represents a significant advancement for industrial applications.","PeriodicalId":16214,"journal":{"name":"Journal of Magnesium and Alloys","volume":"127 1","pages":""},"PeriodicalIF":17.6,"publicationDate":"2024-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142594322","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite their importance, the self-assembly of layered double hydroxides (LDH) with metallic oxide nanoparticles and dicarboxylic acids is constrained by a limited understanding of the formation mechanisms and difficulties in evaluating their anticorrosive performance. In this study, we developed a novel anticorrosive system by intercalating CeNiLDH with a complex of vanadium pentoxide (V₂O₅) nanoparticles and (2E)‑but-2-enedioic acid ((2E)-BDA) on a MgO layer created through plasma-electrolysis of AZ31 Mg alloy. This system was compared with LDH films intercalated with either V₂O₅ or (2E)-BDA alone. The intercalation of LDH with V₂O₅ and (2E)-BDA resulted in a flower-like structure, while modification with their complex led to a more compact, cloud-like formation. These cloud-like structures, driven by enhanced absorption and robust hydrogen bonding throughout the hierarchical network, effectively suppress corrosion by delaying the movement of corrosive anions. This was reflected in a polarization resistance of 1.51 × 10¹⁰ Ω·cm²<strong>,</strong> which is approximately two orders of magnitude times higher than the resistance of the unmodified LDH film (3.41 × 10⁸ Ω·cm²)<strong>.</strong> Additionally, the corrosion current density (<em>i_corr</em>) of the VOBDA sample showed a decrease by four orders of magnitude compared to the unmodified LDH sample, emphasizing the superior anticorrosive performance of this hybrid coating. Density functional theory (DFT) was used to elucidate the bonding and formation mechanisms between LDH and the inorganic-organic complex.","PeriodicalId":16214,"journal":{"name":"Journal of Magnesium and Alloys","volume":"135 1","pages":""},"PeriodicalIF":17.6,"publicationDate":"2024-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142588330","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the primary production of magnesium is highly energy-intensive and environmentally challenging. Solid-state recycling via plastic deformation techniques offers a promising alternative to manufacturing ultrafine-grained magnesium samples with superior characteristics. Given the lack of reviews on the mechanisms of grain refinement during the solid-state recycling of magnesium and its alloys, this paper addresses this gap by offering detailed insights. Through an extensive review of relevant literature, the current paper highlights how plastic deformation techniques facilitate grain refinement during the solid-state recycling of magnesium chips and wastes. In this regard, a grain refinement mechanism during SSR of Mg and its alloys is proposed by the authors, to guide future advancements in sustainable magnesium recycling technologies. This will clarify the benefits of solid-state recycling over traditional methods, such as higher metal yields and better mechanical properties.","PeriodicalId":16214,"journal":{"name":"Journal of Magnesium and Alloys","volume":"17 1","pages":""},"PeriodicalIF":17.6,"publicationDate":"2024-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142588332","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The relationship between the macroscopic-cyclic-deformation behavior and the microscopic responses (particularly twinning and detwinning) at the grain level was established. The general deformation-mechanism evolution in the solution-state (ST) sample was similar to that in the peak-aged-state (PA) sample over fatigue cycles. Both samples plastically deformed by extension twinning during compression, and by a sequential process of detwinning and dislocation motion under reverse tension. The main difference is that in the PA sample, the presence of precipitating particles constrains the twinning/detwinning behaviors, which leads to an increase in the participation of dislocation slip in the plastic deformation and then induces a strengthening effect during cyclic loading. Based on the combination of the previous <em>in-situ</em> ND results and crystal-plasticity model, our work provides a comprehensive analysis of the interaction between the precipitation strengthening and twinning/detwinning mechanism under the whole multi-cycle cyclic loading and their effect on the macro- and micro-mechanical behavior of the precipitate-strengthened magnesium alloys.","PeriodicalId":16214,"journal":{"name":"Journal of Magnesium and Alloys","volume":"247 1","pages":""},"PeriodicalIF":17.6,"publicationDate":"2024-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142579863","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we constructed a magnetic layered component in Mg matrix composite reinforced with reduced graphene oxide (RGO) through an in-situ interface reaction strategy, achieving simultaneous improvement in the strength, ductility, and electromagnetic shielding performance of the composite. The magnetic component is generated by the in-situ reaction of Fe₂O₃ nanoparticles encapsulated on RGO with the Mg matrix. The superior strength-ductility synergy originates from layered heterostructure, which actives non-basal dislocations and enables a stable microcrack-multiplication. The heterogeneous layered structure strengthens the multi-level reflection of electromagnetic wave (EMW) inside the composite. The in-situ interfacial reaction introduces abundant of heterogeneous interfaces into the composites, which improves the interfacial polarization loss ability of the composites. The magnetic RGO layer can provide shape anisotropy that breaks the Snoek limit, thus improving the magnetic loss ability of composite in high-frequency electromagnetic fields. The synergistic action of multiple EMW loss mechanisms improves the electromagnetic shielding performance of composite.

However, their rapid degradation rate has limited widespread use. In this study, we developed a Mg alloy -based mesh designed for calvarial bone defect reconstruction. We modulated the bone formation through the controlled degradation rate of the Mg alloy mesh. To achieve this, the Mg alloy mesh was coated with 2 types of coatings: Zn-d/Ca-P and Zn-d/Ca-P/P. Our findings revealed that, in comparison to the uncoated Mg alloy, both Zn-d/Ca-P and Zn-d/Ca-P/P coatings significantly reduced the degradation rate. The biocompatibility of the coated meshes improved markedly. With the Zn-d/Ca-P coating, there was not only an augmentation in the osteogenic potential of the Mg mesh but also an enhancement in angiogenic capacity. These meshed Mg samples were subsequently implanted into calvarial defects in rats. Bone regeneration was accelerated in specimens treated with Zn-d/Ca-P and Zn-d/Ca-P/P coatings compared to those with the bare Mg mesh. Furthermore, the in vivo assessments indicated that the coated meshes promoted angiogenesis. Nonetheless, the degradation rate of the Zn-d/Ca-P/P coating was slower than that of Zn-B/Ca-P. For applications requiring prolonged mechanical support, the Zn-d/Ca-P/P coating on Mg alloy is recommended, whereas the Zn-d/Ca-P coating is advisable for rapid regeneration where extended mechanical support is not critical.","PeriodicalId":16214,"journal":{"name":"Journal of Magnesium and Alloys","volume":"40 1","pages":""},"PeriodicalIF":17.6,"publicationDate":"2024-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142450157","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MgLi₂Al nanophases and fragmented MgO particles are formed at the bond interface during ARB process, which has a significant positive effect on the interface bonding. With the increase of ARB cycles, the bond interface spacing decreases, DRX mode changes from continuous dynamic recrystallization (CDRX) to geometrical dynamic recrystallization (GDRX), and the Zener-pinning effect is enhanced, which facilitates the grain refinement strengthening. The bond interface can not only effectively hinder the movement of dislocations causing strengthening, but also absorb, reflect and transmission the dislocations causing the improvement of the ductility.
